Enabling Vote Delegation for Boardroom Voting

A lot of decisions are made during boardroom meetings. After a discussion, the head of the board often asks for a quick poll. But what if you cannot join the meeting? So called boardroom voting schemes have been proposed to conduct the poll over the Internet and thereby enabling also those who are not present but available online to participant in the poll. But what if you are not available at this point in time? For important decisions you may want to delegate your vote to a present and trusted board member. In this paper, we show how to extend an existing boardroom voting scheme towards delegation functionality. The new scheme is evaluated against security requirements determined for boardroom voting and security requirements tailored to the delegation process.
